Archaeologists divide the evolution of Native American cultures into the following
approximate time periods:
Paleo-Indian Period (12,500-8,000 years ago)
Archaic Period (8,000-3,000 years ago)
Woodland Period (3,000-1,000 years ago)
Late Woodland Period (1,000 years ago-1600AD)
the Early Contact Period (1600AD-1700AD)
These periods are marked by specific changes in the material culture that has been revealed in the archaeological sites.
